Re: zsh ignores the arguments on its first command.

Peter,

Thanks for the fix.

I was thinking that, in addition,
the construct ${+NAME}
should never cause "unknown parameter",
not even due to failure to load a module
that provides the parameter as a feature,
so an additional fix in the zsh core might be good.
If a module fails to load, NAME should become an
ordinary unset variable, and ${+NAME} should be 0.
